Problems solved by technology

At present, there is no special instrument for artificial rupture of membranes in obstetrics clinics, and needles or vascular forceps are required. When needles are used for artificial rupture of membranes, they need to be clamped between the index finger and middle finger and enter the vagina, which has poor stability. The accuracy is not high, and the operation cannot be performed when the cervix is ​​less than 3cm
When vascular forceps are used for artificial rupture of membranes, due to the limited length of the vascular forceps, the top of the forceps is thicker, and the fetal membrane needs to be clamped to tear, so the size of the tear cannot be controlled, and the one-time success rate is low

Abstract

The invention relates to an amniotic fluid membrane rupture needle which comprises a cylindrical hollow turbine casing. A turbine is arranged in a cavity inside the turbine casing, a column perpendicular to the turbine is arranged at the circle center of the turbine, the top of the column penetrates the turbine casing to be arranged, and the top of the column is provided with a horizontal rocking rod. The top of the turbine casing is provided with a hollow barrel with the two open ends, the barrel communicates with the cavity inside the turbine casing, and the center of the top of the barrel is provided with a membrane rupture needle. The bottom of the turbine casing is provided with a hollow pipe body with two open ends, the pipe body communicates with the internal cavity of the turbine casing, the bottom of the pipe body is provided with a hollow liquid-collecting bottle, and the pipe body communicates with an internal cavity of the liquid-collecting bottle. The amniotic fluid membrane rupture needle is reasonable in structure, convenient and practical, saves time and labor, ruptures a membrane accurately and is safe and efficient, and the size of a gap is controllable.

Description

(1) Technical field [0001] The invention relates to a medical instrument, in particular to an amniotic fluid rupture needle. (2) Background technology [0002] The amniotic fluid was artificially ruptured to observe the degree of turbidity, the purpose is to prove whether there is hypoxia in the uterus. At present, there is no special instrument for artificial rupture of membranes in obstetrics clinics, and needles or vascular forceps are required. When needles are used for artificial rupture of membranes, they need to be clamped between the index finger and middle finger and enter the vagina, which has poor stability. The accuracy is not high, and the operation cannot be performed when the cervix is ​​less than 3cm. When vascular forceps are used for artificial rupture of membranes, because the length of the vascular forceps is limited and the top of the forceps is thicker, the fetal membrane needs to be clamped to tear, so the size of the tear cannot be controlled, and th...
